Read the information in this chapter carefully before you begin the upgrade.
Survivable Remote Gateway (SRG)
An SRG50 system uses the same hardware and is based on the same software as a
BCM50 system. When you apply the SRG keycode, only the SRG functionality is
activated. Therefore, you use the same upgrade process to upgrade BCM50 and
SRG50 systems.
7
Applicable systems
The upgrade applies to systems running:
•BCM50 1.0 (versions 1.00.2.04g and 1.00.2.04j)
•SRG50 1.0
What is new in BCM50 2.0
For a list of new features supported by BCM50 2.0, see the System Overview Guide.
Features not available
The upgrade process does not upgrade the BCM50 1.0 hardware; only the software is upgraded.
Therefore, the BCM50 1.0 hardware cannot support the following features provided in a new
BCM50 2.0 system:
Because the BCM50 router hardware is not upgraded during this upgrade process, the router
functionality remains the same as in BCM50 1.0. That is, all BCM50 1.0 router features
function normally on the upgraded system, and all new BCM50 2.0 router features are not
available on the upgraded system.
